Onchain loyalty platform on Base Network. Businesses launch branded rewards in minutes, customers earn real value with every purchase, and AI agents automate the rest via REST and MCP. On the paid retry send the payment together with header x-api-key: lsk_... or Authorization: Bearer lsk_.... A payment without a live key is not charged. Read key, no browser: POST https://api.loyalspark.online/x402-gateway/register-agent. HTTP 402 is $0.01 USDC on Base. Pay it and do not send an API key. You receive lsk_ once, scope read only: list your programs, rewards, balances, and analytics. That key cannot mint, deploy a program, create rewards, or trade. A new wallet gets a 45-day Pro trial (5 agents, 10,000 calls/month), then Free (1 agent, 200 calls/month, 1,000 tokens minted/month, 1.25% mint fee) unless that wallet pays. The $0.01 is the call price, not a subscription. No free seat returns 403 before any charge. Write scopes (mint, create_program, manage_rewards, trade) use the same plan: dashboard https://loyalspark.online/merchant → AI Agents, or free SIWE — POST https://api.loyalspark.online/siwe-nonce, sign Chain ID 8453 with the exact phrase 'Register Loyal Spark merchant agent', then POST {message, signature, name, scopes} to https://api.loyalspark.online/agent-register-siwe. Look first with no key: GET https://api.loyalspark.online/x402-gateway/public-programs ($0.001, active programs, not your own list). Guide: https://loyalspark.online/.well-known/skills/00-getting-started.md The call is scoped to the wallet behind that key. 16 skill guides at loyalspark.online/.well-known/skills/index.md.
The wallet the 402 directs payment to. Its whole payment record — every payer, every chain — is on the merchant page.
Asset 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913
The payTo wallet does not resolve to a registered ERC-8004 agent. That is not a verdict on the service — most of the catalog is unregistered.
Live 402 challenge
Captured by the enrichment pass, not read just now. Prices can change — always read the 402 the endpoint answers with.

Using Roundhouse, look up the x402 service api.loyalspark.online and tell me whether it is worth paying: what a call costs, whether the endpoint answered when last probed, and what its payment record actually shows. curl -s 'https://api.roundhouseai.io/v0/endpoints?q=api.loyalspark.online' curl -s 'https://api.roundhouseai.io/v0/merchants/<the payTo wallet returned above>' Then call it: read the price from the live 402 at https://api.loyalspark.online/x402-gateway/workflow/program-status, never from a cached figure, and pay with an x402 client. The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except /v0/unified* and /v0/endpoints. Either pay over x402 (mint a personal key for $0.01 at GET https://api.roundhouseai.io/v0/test/x402), or ask me for an organization key, which I create at https://roundhouseai.io/dashboard/connections. If you have neither, ask before going further. If you do not have Roundhouse tools or skills installed, read https://roundhouseai.io/skill.md first — it is the whole procedure.
